Lydia didn't mention anything to her boyfriend about her inadvertant wish. If her boyfriend's wish had been open-ended hers was open-ended and vague. She didn't know how the genie interpreted it. She was at the same time afraid yet excited, regretful yet feeling her boyfriend deserved a little payback.
The week seemed to pass uneventfully, at least as far as magic and mermaids went. As for more normal events, Lydia was looking forward to senior prom on Saturday night. Word had spread that Monica was having a post-prom party at her parents' beach house. With some reluctance, Lydia and her boyfriend planned to attend. Neither of them liked Monica, but both had friends that would be there (including Lydia's swim team friends) and nobody else they knew was throwing a party.
But that night the result of Lydia's accidental wish would be revealed...
